Continuity tests while the conduit is on the reel can be performed with a volt-ohm meter. Continuity testing after the
conduit has been placed can be performed according to the following procedure: Place a locator transmitter at one
end of the run, and connect directly to the wire, use a halo clamp around the conduit, or set the transmitter over the
location of the buried conduit and turn it on. Go to the far end and see if the locator signal can be picked up with the
receiver. If so, continuity exists. If not, follow the signal away from the transmitter until it disappears. That signifies either
a break in the wire or a depth beyond the locator capability.
The tone wire may develop induced foreign voltage during certain field conditions. Adjacent
or parallel power lines may cause a voltage level that can be hazardous. Always test for foreign power prior to
stripping or working with the tone wire, using acceptable test equipment. The wire is 18 AWG copper-clad steel
rated at 30.041 ohm/1,000 ft. 68°F.
